Also the restricting offers for 3 days sounds nice, but the time could also probably be cut down a bit too to not hamper food movement too much when regions are starving.
I disagree with cutting it down to help starving regions as thats the opposite of what we want because the way I see it with the 3 day limit if lords don't want their region to be starving they need to post offers for traders to do. I also disagree with the neccesity of s realm saying they need one of their nobles to be a trader because no matter the system I don't see it being true since I being a trader will surely hang around your realm as long as you want though if I am not making a profit I might start forcing the realm to pay me for coming which is doable.
